I love the TDS system - im trying to become America's poorest sportsman as I think I have over 20 of them now. I only have 1 of the 6-18's though, as I believe 12x is plenty of top end magnification to shoot out to 800 yards with the 2-12 Z6 or 4-12 AV. Sounds like you got it figured out - you got good advice above (other than the guys who claimed turrets were better). And Dirtfarmer probably knows it, but his statement above about first focal plane reticles needs to be corrected in that the crosshairs get THICKER, not thinner when you crank the power up on a FFP reticle. I have tried FFP like the 3-12 PV and the Schmidt and Bender 4-16 TDS and for me, they cover way too much of the target when cranked up which is why I prefer the 2-12x50 Z6 and 4-12x50 and 3-10x42 AV's.

Thanks for the tip about the ballistics app Sakoluvr- going to try that out.
